Description

[0001] The invention relates to a method for producing a data page, a data page for a book-like document, and a device for producing such a data page.

[0002] German patent application DE 10 2012 213 913 A1 discloses a method for producing a data page for a book-like document. In this method, a data carrier and a flap made of a textile material are aligned so that the flap and the data carrier overlap in an overlapping area. An ultrasonic device then joins the flap and the data carrier together in the overlapping area. Using a sonotrode of the ultrasonic device, projections acting as energy direction transmitters melt at least an outer layer of the data carrier to weld the flap to the data carrier. During this joining process, the sonotrode is pressed against an anvil of the ultrasonic device, with the anvil and the sonotrode acting on the overlapping area.

[0003] US patent 2014 / 0265301 A1 describes a book-like document with a data page and an inner page. The data page comprises a data carrier that is connected to a flap by friction welding in an overlapping area.

[0004] From DE 10 2014 217 716 A1, a method for producing a data page and a data page itself are further disclosed. In the overlap area, the flap, made of textile material, is connected to at least one outer layer of the data carrier. The outer layer is partially melted, and the textile flap is at least partially pressed in. To increase the security of such a data page, a predetermined separation line in the form of a series of perforations or holes is incorporated into the flap. This predetermined separation line is incorporated into the flap before it is connected to the data carrier. Before connecting the flap to the data carrier, the flap with the predetermined separation line is aligned with the data carrier such that this line lies outside the overlap area and separates the overlap area into a connection area.The connection area is formed by the section of the tab that protrudes freely from the data carrier and serves to attach the data page to the book-like document or a book block. This predetermined breaking point ensures that, in the event of tampering, the data carrier is separated from the connection area of ​​the tab.

[0005] The invention is based on the objective of proposing a method for producing a data page as well as a data page for a book-like document and a device for producing such a data page, whereby an alternative welding of the flap to the data carrier for producing the data page is made possible.

[0006] This task is solved by a method for producing a data page for a book-like document, in which the flap and the data carrier are joined together in the overlap area by friction welding. The first or second tool for friction welding is excited by a vibration whose oscillating, translational relative motion is aligned parallel to the direction of extension of the data page or the flap. This excitation of the first or second tool with the oscillating, translational relative motion results in linear vibration welding as friction welding, in which melting occurs in the contact zones between the flap and the data carrier in the overlap area. This melting of the flap and / or the data carrier at the contact zones allows a molten metal flow to occur, leading to a metallurgical bond.After the oscillating, translational relative movement has ended, the overlap area can be cooled, preferably under pressure, so that a material-bonded connection is created between the tab and / or the data carrier in the overlap area.

[0007] Preferably, the data side and the tab are clamped to the first and second tools, respectively. This allows for simple and secure attachment of the data side and the tab to the respective tool. Simultaneously, when the oscillating, translational relative movement is initiated by one of the two tools, secure engagement of one joining partner and secure fixation of the other joining partner can be achieved. The joining partners are, on the one hand, the data side and, on the other hand, the tab.

[0008] According to an alternative embodiment, the data side or the tab can be clamped to the first tool, and the tab or the data side can be held in position relative to the second tool by friction. This alternative embodiment has the advantage of reducing the preparation time for friction welding, since only one of the two joining partners needs to be fixed to the first tool by a fastening device, such as a clamp or positioning in a fixture.

[0009] Preferably, the data side and the tab are each held against their respective tools by friction. Preferably, the data side rests on a support surface of the second tool. The tab is connected to a working surface on the first tool. Due to the respective material friction of the tools assigned to the joining partners and a lower material friction between the joining partners, they can be held fixed in their position relative to the tools, so that one of the two joining partners can be subjected to an oscillating, translational relative movement for the friction welding process.

[0010] In particular, it is provided that a coefficient of friction is selected between the material of the tab and the first tool which is excited to oscillating, translational relative motion, which is greater than a coefficient of friction between the tab and the data side.

[0011] Preferably, the working surface of the first and / or second tool and the bearing surface of the second tool are roughened. For example, the surface can be formed with a grain or a needle-like texture. Such a grain can be produced, for example, by a chemical process, an electrical ablation process, or by grinding the respective surface.

[0012] Advantageously, the first or second tool is controlled by an oscillating, translational relative movement, aligned in the longitudinal direction of the overlap area, while the other tool remains stationary. This has the advantage that the freely projecting area of ​​the tab outside the overlap area remains unaffected along a longitudinal side of the data carrier, which defines the boundary of the overlap area with the tab.

[0013] Furthermore, it is preferably provided that the first or second tool is heated. This heating, for example to a temperature of at least 130°C, has the advantage that faster melting of the at least one material to be welded can occur, which attacks the heated tool or is opposite it. For example, in the case of a tab made of a polymeric material, it is preferably provided that the heating temperature is set at or above the glass transition temperature.

[0014] According to a preferred embodiment of the method, it is provided that during the application of the oscillating, translational movement to at least one tool and / or after the termination of this relative movement, the tools are subjected to a pressure of at least 10 N / cm². 2 , especially in a range of 10 N / cm 2 up to 50 N / cm 2, are applied to the overlap area between the tab and the data carrier. Particularly after the relative movement, a particularly strong bond between the tab and the data carrier can be created during the cooling phase under pressure.

[0015] Furthermore, the oscillating, translational relative movement takes place at an operating frequency of 100 to 500 Hz. This allows for rapid heating and melting in the contact zones of the joining partners.

[0016] In particular, the amplitude of the relative movement is controlled with a length of 0.3 to 4 mm. The amplitude is preferably controlled by matching it to the operating frequency. For example, an operating frequency of 100 Hz is advantageous with an amplitude of approximately 1 to 4 mm. For example, an amplitude of 0.35 to 2.0 mm can be controlled at an operating frequency of 300 Hz.

[0017] The object underlying the invention is further solved by a data page for a book-like document, which comprises a data carrier and a flap that are joined together in the overlap area by a friction weld. Compared to ultrasonic welding known from the prior art, such a friction weld allows for a wider selection of materials, particularly their structures. Moreover, a very clean weld can be created within a very short time.

[0018] The data carrier is preferably manufactured from one or more layers. Preferably, at least one layer is formed from a polymeric thermoplastic material, which is provided in the overlap area. Such a polymeric material supports the material-bonded connection in this friction welding process.

[0019] In particular, at least one outer layer is made of polycarbonate.

[0020] According to a preferred embodiment of the method, the tab is formed from a polymeric material and / or a textile material and / or a multilayer composite material, in particular from one of the aforementioned materials. Due to the oscillating, translational relative movement of one of the two joining partners, the tab of one joining partner can, for example, also consist of a film made of a polymeric material. In the case of such a film, which is to be joined to a layer of polymeric material of the data carrier, the opposing contact zones can be melted and bonded together. Textile materials can also be used, allowing molten material from the data carrier layer to penetrate the woven openings of the textile material.

[0021] The flap is preferably made of a polyester fabric, in particular a monofilament polyester fabric. This allows for both a good weld in the overlap area and a secure integration of the data page into a book block via the flap. In such a book block, several inner pages are joined together by a seam using a flap of the data page.

[0022] The length of the tab is shorter than one longitudinal side of the data carrier. These narrow end faces of the tab are recessed relative to the end faces of the data carrier. Preferably, the length of the tab is shortened by at least the amplitude of the oscillating translational relative movement with respect to the longitudinal side of the data carrier. This ensures that the tab remains in contact with the data carrier along its entire length during the friction welding process, forming contact zones. This results in improved friction welding that requires no post-weld rework.

[0023] The object underlying the invention is further solved by a device for producing a data page, in particular for a book-like document, which welds a flap to a data carrier and has a first tool with a working surface and a second tool with a support surface, wherein the working surface and the support surface are aligned facing each other and are opposite each other, wherein the first tool can be controlled in the plane of the working surface or the second tool in the plane of the support surface by an oscillating translational relative movement. By controlling one of the two tools by a vibration movement lying in the plane of the working surface or the support surface, melting can be achieved in the contact zones of the data page and the flap in the overlap area.This friction welding process has the advantage that a flat surface can be formed on the tab on one side and a corresponding surface on the data carrier on the other in the overlap area. Friction welding prevents indentations from either outer surface on the tab or the data carrier caused by energy direction sensors, such as those protruding from an ultrasonic sonotrode.

[0024] According to a first embodiment, the device has a fastening device for fixing the tab or data carrier to the first and / or the second tool. Such a fastening device can be a clamping or tensioning device, which enables easy attachment of the tab or data carrier to the respective tool. Alternatively, a positive-locking receptacle can be formed on the tool.

[0025] Alternatively, the working surface of the first tool and / or the contact surface of the second tool can be roughened. This allows for easy positioning of the tab and / or the data carrier relative to the respective tool for subsequent friction welding.

[0026] It is also possible for one tool to have a fastening device and the other tool to have a roughened surface. In particular, it is provided that the lower tool, which has the contact surface, includes a roughened surface. The upper tool can preferably have a fastening device. This allows, for example, for easy feeding of one joining partner to the other for the subsequent friction welding process.

[0027] According to a further preferred embodiment of the device, the length of the tool that is set into oscillating, translational relative motion is equal to or greater than the length of the overlap area. This allows a complete friction weld to be created over the entire length of the shortened joining partner.

[0028] Furthermore, it is preferably provided that the width of the tool, which is displaced in the oscillating, translational relative motion, is equal to or wider than the overlap area. The width of the tool is defined as its extent perpendicular to the oscillating, translational relative motion.

[0029] The invention, as well as further advantageous embodiments and developments thereof, are described and explained in more detail below with reference to the examples shown in the drawings. The features that can be derived from the description and the drawings can be applied individually or in any combination according to the invention. The drawings show: Fig. 1.

[0030] In Fig. Figure 11 is a book-like document, in particular a security document, shown in perspective. This book-like document 11 is, for example, an identification document such as a passport. The document 11 includes, for example, a book cover 12. An endpaper 14 may be provided on an inside page of the book cover 12, which is attached to the book cover 12. A data page 17 and one or more inside pages 18 are joined together by a seam 16 to form a book block 15. If a book cover 12 and, in particular, the endpaper 14 are provided, this endpaper 14, or this endpaper 14 together with the book cover 12, can also be joined by the seam 16 to form the book block 15. The inside pages 18 of the book-like document 11 may, for example, serve to hold visas, stamps, or other entries. The data page 17 consists of a data carrier 20 and a flap 23 attached to it.The data page 17, in particular the data carrier 20, can, for example, be designed according to the ICAO standard, in particular ICAO Doc 9303, 7th edition, and include an image 19 of the document holder, an OCR-readable ICAO zone 21 (also called "machine-readable zone" or MRZ), and further personalization data 22. The personalization data 22 is provided within the data carrier 20. The flap 23 of the data carrier 20 extends over the seam 16. This flap 23 also includes a seam area in which the seam 16 is formed. In addition to or as an alternative to the seam 16, an adhesive and / or welded connection can be provided to bind the flap 23 into the book-like document 11, in particular the book block 15.

[0031] In Fig. Figure 2 schematically shows a side view of data page 17. The data carrier 20 can, for example, include a transponder module 24, which comprises an IC chip 25 and an antenna 26. In addition, or alternatively, further electronic and / or other security elements, in particular diffractive security elements, can be integrated and / or applied.

[0032] The tab 23 is connected to the data carrier 20 by forming an overlap area 30. The tab 23 comprises a woven tape material, which is preferably connected to an outermost layer or layer of the data carrier 20 by welding. In particular, the tab 23 can consist of the woven tape material, preferably a PET fabric. Regarding the connection of the tab 23 to the woven tape material for the tab 23 and to the data carrier 20, as well as the structure of the data carrier 20, reference is made in full to DE 10 2012 213 913 A1.

[0033] The data side 17 has an upper and lower front edge 35, 36 as well as a right and left front edge 33, 39. The tab 23 has an upper and lower edge or an upper and lower front face 37, 38, which may be set back inwards relative to the front edges 35, 36.

[0034] In Fig. 3 is a schematic sectional view along line II-II in Fig. Figure 2 shows a first exemplary assembly of the data page 17 before lamination. After lamination, all layers of the data carrier 20 and the tab 23 are bonded together to form a data page 17. In particular, a monolithic structure is present.

[0035] The data carrier 20 comprises a front-side binding 28 and a back-side binding 29, wherein, for example, the flap 23 is applied to the front-side binding 28. This forms an overlap area 30. Opposite this, a protruding area 31 is formed, along which the seam 16 runs for binding the flap 23 into the document 11. The front-side binding 28, which can also be referred to as the data-side binding, comprises at least one layer 32. The layer 32 can also be printable. Preferably, several layers are provided to form the front-side binding 28, such as a print layer, which can be opaque, with a further layer applied to the print layer, which is advantageously transparent.

[0036] The back cover 29 can also include at least one layer 34 or have an analogous or different structure to the front cover 28. The front and / or back cover 28, 29 can include various security features, such as a CLI (Changeable Laser Image) or MLI (Multiple Laser Image) feature, as well as printed images with optically variable color (OVF) or the like.

[0037] At least one layer 32 of the front-side booklet 28 and / or at least one layer 34 of the back-side booklet 29 may be made of one or more plastics (polymers). In particular, these include or consist of polycarbonates (PC). Other alternatives may be: bisphenol-A polycarbonate, carboxy-modified PC, polyethylene terephthalate (PET), its derivatives such as glycol-modified PET (PETG), polyvinyl chloride (PVC), polyvinyl butyral (PVB), polymethyl methacrylate (PMMA), polyimide (PI), polybutylene terephthalate (PBT), polyvinyl alcohol (PVA), polystyrene (PS), polyvinylphenol (PVP), polypropylene (PP), polyethylene (PE), thermoplastic elastomers (TPE), in particular thermoplastic polyurethane (TPU), acrylonitrile butadiene styrene copolymer (ABS), and / or their derivatives, or made of paper and / or cardboard or of mixtures of the aforementioned materials.

[0038] Tab 23 is according to detail X in Fig. 2 enlarged in a top view in Fig. Figure 4 shows that, according to this embodiment, the flap 23 is formed as a woven fabric. This fabric can comprise weft and warp threads 43, 44. These are preferably formed as monofilaments. Fabric openings 45 are formed between the warp and weft threads 43, 44.

[0039] A thermoplastic material, in particular a polyester, for example polyethylene terephthalate (PET), is preferably used as the woven tape material for the tab 23. The melting point or glass transition temperature of the fusible material of the woven tape material is preferably adapted to the material properties of the data carrier 20. The melting and / or glass transition temperature of the tab 23 and the melting and / or glass transition temperature of the data carrier 20 are matched so that when the tab 23 is connected to the data carrier 20, the woven tape material of the tab 23 is not yet softened, but at least layer 32 is, so that the fabric opening 45 is at least filled and / or enclosed by the softened material of layer 32. The textile material of the tab 34 can also be made of glass fibers.

[0040] From the schematic sectional view according to Fig. Figure 3 shows that the tab 23 is applied to one side of the top surface of layer 32, wherein in this embodiment the layer 32 comprises a receiving area 46. This receiving area 46 is formed by a reduction in the wall thickness of layer 32. This allows, in principle, an almost stepless integration of the tab 23 in the overlap area 30 with an adjacent surface of layer 32 of the data carrier 20. Similarly, the tab 23 can also be attached to layer 34.

[0041] The tab 23 can alternatively be formed as a textile surface structure in the form of a woven, knitted, or felted fabric or nonwoven fabric, also from a composite of filaments, in particular fibers, yarn, threads or the like.

[0042] The tab 23 can furthermore be formed from a layer of a polymeric material or from several layers of polymeric materials, in particular from different polymeric materials. For example, a thermoplastic polymer, in particular a polyester, such as polyethylene terephthalate (PET) or a thermoplastic polyurethane (PTU), can be used as the polymeric material. Fibers, yarns, or filaments, which are processed into a fabric, can also be formed from such materials. The melting point for the glass transition temperature of the fusible material of such a tab is preferably adapted to the material properties of the at least one outer layer of the data carrier.

[0043] Alternatively, the flap can also be made of textile materials, such as cotton, a cotton-polymer blend, or especially a cotton-polyester blend.

[0044] The flap can also be formed from a continuous, flat layer of a polymeric material. Alternatively, the flap can consist of a continuous, flat layer of a polymeric material with a textile material applied to one side. Finally, the flap can have a sandwich structure in which a textile material is bonded on both sides to a layer of a polymeric material.

[0045] In Fig. Figure 5 shows an alternative embodiment for attaching the tab 23 to the data carrier 20 to form the data side 17. The receiving area 46 is not provided. Depending on the mesh size of the tab 23 and / or the pressure of a laminating or welding tool, the tab 23 penetrates the overlap area 30 after the tab 23 and / or the layer 32 have been at least partially melted or fused.

[0046] In the Fig. 6, Fig. 7 and Fig. Figure 8 shows different views of a device 51 for producing the data page 17, in which the tab 23 is connected to the data carrier 20 in the overlap area by friction welding.

[0047] This device 51 comprises a first tool 52, which is also referred to as the upper tool. Opposite this is a second tool 53, which is also referred to as the lower tool. The first tool 52 has a working surface 54 that faces the second tool 53. The second tool 53 has a support surface 57 that faces the working surface 54. Preferably, the working surface 54 and the support surface 57 are parallel to each other. From the layer applied to the device 51 according to Fig. Figure 7 shows that the length of the first tool 52 extends beyond the length of the tab 23 at least in the overlap area 30. The width of the first tool 52 is such that its width corresponds to or extends beyond the overlap area 30. If the width of the first tool 52 is greater than the width of the overlap area, the first tool 52 is preferably arranged such that it is offset inwards towards the data carrier 20 relative to an end face 39 of the data carrier 20. The end face 39 of the data carrier 20 defines the protruding area 31 of the tab 23 towards the data carrier 20.

[0048] The friction weld can be made directly adjacent to the end edge 29 of the data carrier 20 in the overlap area 30. Alternatively, a strip-shaped section can also be provided between the end edge 39 and the tab 23 and data carrier 20, which are joined by friction welding.

[0049] The working surface 54 of the first tool 52 and the support surface 57 of the second tool 53 are preferably roughened. This roughening of the working surface 54 and the support surface 57 enables the data carrier 20 and the tab 23 to be fixed in place by friction. In the exemplary embodiment, the data carrier 20 rests on the support surface 57 of the second tool 53. The tab 23 rests against the working surface 54 of the first tool 52. Alternatively, the arrangement of the data carrier 20 and the tab 23 can be reversed.

[0050] In this embodiment, the first tool 52 is set into an oscillating, translational relative motion, as indicated by the double arrow 58, to produce the friction weld. This oscillating translational relative motion lies in the plane of the working surface 54 or is parallel to the working surface 54. The second tool 53 is preferably stationary during the friction welding process.

[0051] In order for the oscillating, translational relative movement to be transferred to the tab 23, while the data carrier 20 remains stationary relative to the support surface 47, it is preferably provided that the coefficient of friction between the working surface 54 of the first tool 52 and the tab 23 is greater, in particular several times greater, than the coefficient of friction at contact zones between the tab 23 and the data carrier 20. The coefficient of friction between the support surface 56 of the second tool 53 and the data carrier 20 can correspond to the coefficient of friction between the tab 23 and the working surface 54 of the first tool 52.

[0052] In Fig. Figure 9 is a schematic side view according to an alternative embodiment of the device 51. Fig.Figure 6 shows that in this embodiment, a fastening device 62 is provided on the first tool 52. For example, this fastening device 62 can be designed as a clamping device. This holds the tab 23 firmly clamped to the working surface 54 of the first tool 52. The working surface 54 itself can be flat or roughened.

[0053] The second tool 53 preferably also has a fastening device 62. This fastening device 62 can alternatively be formed by a rim, so that after the data carrier 20 is inserted, the data carrier 20 remains held securely within the rim. In particular, the data carrier 20 remains fixed in its position with respect to relative movement as indicated by the double arrow 58.

[0054] Alternatively, it can be provided that one of the two fastening devices 62 on the first tool 52 or the second tool 53 is formed by a previously described embodiment in which it has a roughened or needle-like surface.

[0055] To create a friction weld, the data carrier 20 is placed on the support surface 57 of the second tool 53. Subsequently, the tab 23 is positioned against the data carrier 20, forming the overlap area 30.

[0056] The joining partners, namely the tab 23 and the data carrier 20, rest against each other. Contact zones are formed between them. The first tool 52 is excited by an oscillating, translational relative movement, preferably under a defined pressure. The operating frequency of the relative movement can be in the range of 100 to 300 Hz. The amplitude can be, for example, from 0.35 mm to 4.0 mm. The defined pressure can be, for example, from 10 to 50 N / cm². 2 After the contact zone has melted, the first tool 52 is stopped. The contact pressure of the first tool 52 on the second tool 53 can be maintained or slightly increased. A metallurgical bond can be created by the cooling of the molten contact zones of the tab 23 and the data carrier 20.

[0057] Preferably, the first tool 52 and / or the second tool 53 can be heated. Preferably, the first tool 52, which is prepared for the tab 23, is heated. This ensures that the melt is not stopped, at least by the uppermost layer of the data carrier facing the tab, as soon as it flows through the fabric of the tab and comes close to the tool 52, 53. This allows for improved interlocking between the data carrier and the tab in the overlap area. Reference symbol list 11 Book-like document 12 Book cover 13 14.
